The invention describes methods and apparatus for creating permanent occlusion of body lumens such as the fallopian tubes. The methods and apparatus use non-surgical approaches to deliver permanent implants which create acute occlusion of desired body lumens which resolve to permanent occlusions of the lumens.

A piston ring mounted in the ring groove of an aluminum alloy piston does not cause aluminum adhesion during the long-term use. The piston ring includes a resin film deposited on at least one of an upper face and a lower face. The resin film contains from 0.5 to 20% by volume of carbon black particles and from 3 to 30% by volume of solid lubricant particles with respect to the total volume of the resin film. The carbon black particles preferably contain one or both of graphitized carbon black particles and composite graphite black particles.

Disclosed is an automated insert feeding system and related methods, capable of removing bulk-packaged items from a tray or other package, and separating the bulk-packaged items individually for distribution into individual packages in high speed reliable fashion. The disclosed systems can also be loaded with multiple packages of the pre-packaged items for automatic feeding into the system which allows human operators to load several packages and allow the system to work unattended, thereby reducing man-hours spend on the process.

A surface wave chemical detector comprising at least one surface wave substrate, each of said substrates having a surface wave and at least one measurable surface wave parameter; means for exposing said surface wave substrate to an unknown sample of at least one chemical to be analyzed, said substrate adsorbing said at least one chemical to be sensed if present in said sample; a source of radiation for radiating said surface wave substrate with different wavelengths of said radiation, said surface wave parameter being changed by said adsorbing; and means for recording signals representative of said surface wave parameter of each of said surface wave substrates responsive to said radiation of said different wavelengths, measurable changes of said parameter due to adsorbing said chemical defining a unique signature of a detected chemical.

The invention discloses a bypass filtration system for filtering impurities in water. The bypass filtration system comprises a water filtering tank and a settling tank arranged on the outer side wallof the water filtering tank, wherein a first water inlet hole is formed in the upper side wall of the water filtering tank, a first water outlet pipe is arranged at the bottom of the water filtering tank, a first through hole is formed in the side wall of the water filtering tank, a second through hole matched with the first through hole is formed in the side wall of the settling tank, a rotatingshaft is arranged on one side, close to the water filtering tank, of the settling tank in the vertical horizontal direction, a foldable filtering assembly is arranged on the side wall of the rotatingshaft, the filtering assembly is located in the water filtering tank in the initial state, the filtering assembly is completely unfolded and blocks the cross section of the water filtering tank, and the part, located in the water filtering tank, of the filtering assembly is folded in the direction close to the settling tank in use. Compared with the prior art, the bypass filtering system providedby the invention has the advantages that by arranging the foldable filtering assembly, impurities deposited on the filtering assembly are transferred into the settling tank, so that the impurities areprevented from being deposited on the filtering assembly to influence the filtering effect.

The invention discloses a waste weft yarn intelligent processing device of a water-jet loom. The device comprises a main body bin, a top cover is installed at the top of the main body bin, a servo motor is installed at the center of the top of the top cover, a rotating bin is arranged in the top cover, and a partition plate is installed in the middle of the interior of the rotating bin. Through holes are evenly formed in the bottom of the partition plate, and the output end of the servo motor is in transmission connection with the middle position of the top of the partition plate. Through cooperative use of a collecting assembly, the top cover, filter cotton and the rotating bin, the servo motor is controlled to drive the whole rotating bin to clockwise rotate by 180 degrees, then an electric lifting rod is controlled to be shortened, then an air pump is controlled to suck air, so that waste weft at the top of the first set of filter cotton sequentially passes through a semicircular bin, a telescopic pipe and a connecting pipe and then enters a collecting bin, only the waste weft in the collecting bin needs to be cleaned regularly, treatment of the waste weft through the device does not need to be stopped, and therefore continuous and normal work of the water-jet loom is guaranteed.

The invention discloses building board pouring equipment. The building board pouring equipment comprises a conveying belt used for conveying plate frames; a lifting assembly slidably connected to a transverse guide rail; a pouring device mounted at the output end of the lifting assembly, wherein side transverse moving devices are mounted on the left side and the right side of the pouring device; two groups of lifting arms respectively mounted on the side transverse moving devices and driven by a rotating motor to rotate; and two sets of cleaning devices installed at the output ends of the lifting arms correspondingly.

The invention discloses a liquid subpackaging device for clinical examination, which comprises a main body, a test tube and a filter screen. A hand wheel is arranged above the main body, and the right side of the hand wheel is connected with a first gear. An indented column is arranged below the right side of the gear, and the gear is tightly attached to the indented column. A rubber plate is fixed below the indented column, and the indented column and the rubber plate are bonded by glue. The test tube is installed in the main body, and soft plates are arranged on the left side and the right side of the test tube correspondingly. Springs are connected to the right sides of the soft plates, and the soft plates and the springs are connected by welding. A fixing plate is arranged below the springs, and the fixing plate and the main body are connected by welding. Scales are arranged on the outer surfaces of the soft plates. The filter screen is mounted below the test tube. The liquid subpackaging device for clinical examination is provided with the scales, so that a doctor can make a certain judgment by watching the scales when taking liquid in the test tube, and the doctor can take the liquid more accurately.
